In a small bowl, stir together mayonnaise and mustard - cover and set aside.

To prepare burgers

Preheat grill

In a food processor, add chickpeas, scallions, bread, almonds, ginger, garlic and cumin - season with salt and pepper. Pulse until roughly chopped - remove about half of the mixture to a medium bowl. Add egg to the food processor and process until smooth, scraping down the sides as needed. Add to the mixture in the medium bowl and mix well. Evenly divide the mixture into 4 parts and shape each into a 3/4" thick patty.

Brush each side generously with oil - grill until heated through and marks appear, about 3 to 5 minutes per side. Remove and serve the burgers on English muffins with spinach or lettuce and the sauce.
